To all the rotary guru's and experenced guys
 

i was just wondering where you guys get all your knowledge from. hands on? books? this site? i have anyways wanted to know how my engine works down to the last bolt and where everything goes... someone just always as the awnser.. i am just curious becuase i would love to go indepth into working on my car more.. and thanks for helping me and everyone on this site!!

well you could go get a maintance book there is an overhaul section. I like the chiltons one, but the mazda service book is good too

Get a manual, and get into the car.
Nothing will get you knowledge like experience.
Never fear you can't do something.

This forum!! manuals.. And acually doing the stuff.. (rebuild!!! woot)

My sources over the years:
Thousands of car magazine articles
Hundreds of technical books
Dozens of knowledgable people (join a car club)
Hundreds of websites
15 years of scraping knuckles on cars
Too much time here!

The best advice I can give if you want to know about these cars is to get the Factory Service Manual (buy or download) and the Haynes manual and read them. Don't just refer to them when you have a problem; actually sit down and read them. You'll be amazed what you learn about your car.

My grandfather was a Mazda service manager from the early 70's to the late 80s, and three of my uncles were Mazda techs :)

I have built several cars.
always keeping one available for reference.

Also, go to www.rotaryengineillustrated.com

then search for RX-7 webrings.
check the sites.
bookmarks alot of things.

Oder some of the hardback books available online at Ebay about these cars.

Also theres one available now at Amazon.

Get a copy of the Haynes and FSM and read them in your spare time and while your on the toilet (my fav). Pop your hood and identify every part. Understand how each part affects the running and performance. Learn where the hoses go, and what they carry. Jack up the car onto jackstands and identify everything underneath. Kinda like studying for a history test or something, because it's all there for you, you just need to learn. Most of all, repair everything that you can with your given capacity. Don't be afraid to take off some big things attached to the engine. Sure it all looks complex, but everything for the most part is only held on by bolts :).

Oh ya, and if you don't bleed while working on your car, you don't love it enough ;).

I have learned it from doing it. My basic knowledge came from watching my dad work on his biplanes and now Mig-17 and Venom. www.venmig.com :)

Then pulling the engine twice on my TII has lead to rapid knowledge increases.

doing stuff on my car, mainly this site, Mazdaspeed7, maintenence manual..... that bout covers it

Like everybody is saying.......just dig in!!

Get any books you can find and don't be afraid to tackle anything on these engines. They are not really that complicated.

This forum is an unbeliveable source of information. Anything you are wanting to know, just do a search on here for what you are looking for and you are bound to find multiple threads on here pertaining to the topic.

If you can't find it, post a question and you'll have answers within an hour usually...sometimes even pictures too.

ditto !


Also do not be afraid to experiment in a calculated way, example.

I posted under the single turbo forum what fuel pressure (base) everyone runs just out of interest.

I today went and tested many ND (Jap injectors mazda use) and found that they WILL run no problem at up to 100psi static pressure ! Simple things like this and researching all related systems will let you do things that others say is impossible.

My case in point, I have a Bosch 044 motorsport pump that flows 4.2 Lt of Fuel @ 100psi, my normal 12ATURBO injectors flow 720cc/min@40psi static fuel pressure, Now with my Malpassi 1:1 rising rate regulator my maximum fuel pressure under boost will not go over 90psi (& pump will draw 12.2amps instead of 8amps of current) just by turning up my static fuel pressure to 70psi I turn these 720cc/min injectors into 900cc/min injectors, just by doing something different and totaly within the capacity of related systems.

Be open to new or different ideas, do plenty of double checks on data and be analytical, it will save you money in the long run by avoiding unecessary failures.

Try to do a lot of you're OWN testing to verify data, it is hard to become an expert when you are a messanger for other peoples experiences.

A WARNING, IT WILL BECOME YOU"RE LIFE LONG OBSESSION i.e. ROTARIES....BUILDING ENGINES AND TUNNING THEM !!!!!

The question is...&nbsp Do you see gains in fuel with such high fuel rail pressures? :)

We've seen gains on the ND top-feeds all the way up to 70psi, but get no more gains over 70psi of fuel rail pressure.

Yes, yes, and yes. :)

Ya, the cool thing is with the forum no matter how much you know, even if you think you know everything you can always learn more. But beware, it helps to always think for your self cus there is a lot of mis information on here and you need to filter it befor you go and take it as your own knowledge. But generaly just doing the stuff realy works well and having some good conversations with people that realy know what they are doing helps also. Any ways ya as far as just learning how the motors work just look at the pics and try and figure it out otherwise just ask us on here and most of us are glad to answer even the beginner questions.

I got linear gains all the way to 100psi....

At which point pump current draw is getting to high.

So If the pump can deliver the flow at this pressure 100psi (total) pressure then these injectors will handle it. i.e. 100psi total - boost (20psi) = 80psi static.
